[0002]

2. Description of the Related Art In general, a flat panel display is a flat panel type image display, such as a liquid crystal display, a plasma display, and the like.
There are electronic light emitting devices and the like. The flat panel display has an advantage that the power consumption is very small as compared with other devices, it can be produced in various sizes from ultra-small to large, and the display pattern can be diversified. Therefore, the flat panel display is very important in the field of display devices.

A conventional flat panel display comprises an upper substrate and a lower substrate.
The substrate is made of a transparent material such as glass or plastic to allow light to pass therethrough, and is made in a flat plate shape so that light passing therethrough travels in parallel.

In the conventional flat panel display device formed as described above, the flat panel display device has a large size (for example, 100 pixels in one direction).
cm (40 inches or more), the area of the substrate must be increased. As the area of the substrate increases, the thickness of the substrate must be increased in order to keep the substrate flat. The thick substrate becomes heavy, making the manufacturing process of the flat panel display difficult, reducing the transmittance of display light, and increasing the cost.

As described above, according to the present invention, even when a flat panel display device is manufactured in a large size, the thickness of the substrate itself is not increased, and at least one surface of the upper and lower substrates, if necessary, Reinforcement becomes possible only by attaching a reinforcing structure to the lower surface. In addition, in the case of a large flat panel display, since a thin substrate is used without having to increase the thickness of the substrate as in the conventional case, light passes through the thin substrate. Since the rate does not decrease and the thickness of the substrate does not need to be increased, the cost of the substrate can be reduced. Furthermore,
According to the present invention, since the grounding portion is attached to the reinforcing structure, the flat panel display can block electromagnetic waves generated from inside.

It is preferable to use a transparent glass or plastic as a material of the hollow polygonal pillars forming the reinforcing structure because the viewability of the display device is not hindered.

If hollow hexagonal columns are used as the hollow polygonal columns forming the reinforcing structure, the hollow hexagonal columns can be arranged closely adjacent to each other, and a strong strength can be obtained in spite of many hollow portions of the polygonal columns. Can be
